Spectrum-Efficient Distributed Compressed Sensing Based Channel Estimation for OFDM Systems Over Doubly Selective Channels

IEEE Access, 2019
In this paper, we deal with channel estimation (CE) for high-mobility orthogonal frequency division multiplexing (OFDM) systems. To make the numerous (unknown) estimation for the high-mobility OFDM systems practicable, the channels are assumed to be time-

A Versatile Pilot Design Scheme for FDD Systems Utilizing Gaussian Mixture Models [PDF]

IEEE Transactions on Wireless Communications
In this work, we propose a Gaussian mixture model (GMM)-based pilot design scheme for downlink (DL) channel estimation in single- and multi-user multiple-input multiple-output (MIMO) frequency division duplex (FDD) systems.

Ocean Plankton Biomass Estimation with a Digital Holographic Underwater Glider

Journal of Marine Science and Engineering, 2022
Accurate quantitative plankton observation is significant for biogeochemistry and environmental monitoring. However, current observation equipment is mostly shipborne, and there is a lack of long-term, large-scale, and low-cost methods for plankton ...

Joint Mutual Coherence and Total Coherence Pilot Design for OFDM Channel Estimation

IEEE Access, 2019
Existing works design the pilot based on the mutual coherence criterion or total coherence criterion alone. However, using the mutual coherence criterion or total coherence criterion alone to design the pilot will yield the sensing matrix which ...

Multiuser Massive MIMO Systems With Time-Offset Pilots and Successive Interference Cancellation

IEEE Access, 2019
This paper proposes time-offset pilots for a single-cell multiuser massive multiple-input multiple-output (MIMO) system and studies its performance under the minimum mean-squared error channel estimator and successive interference cancellation.
